Abstract
In which we enter into the world of interwoven family relationships, love, and marriage. The classical “Looking at unmarried people” puzzle has been adapted here for the television series “Friends”. In this puzzle, Monica is looking at Ross, Ross is looking at Rachel. Monica is married; Rachel is not. Is a married person looking at an unmarried person? The answer may seem difficult since we do not know if Ross is married or not. A fan of the “Friends” series would know that even Ross has some difficulties to figure out if he is married or not. You do not have to worry since this is an easy one for Prover9. The chapter continues with puzzles related to lying within mariage, or puzzles asking you to figure out various family relationships.
